I like solving Sudoku puzzle.
Sudoku is a 9x9 grid that contains nine smaller 3x3 grids. The object of the puzzle is to get all of the numbers one to nine into each of the 3x3 boxes and also into each row and each column. As there are only nine squares in each box, row or column, there is no room for repeating any numbers.
It is a bit of a mystery at first, and a challenge. Then it is a problem that we think we can solve. Then when we do find an answer, it gives us a sense of achievement and pride.
